Hello,
I didn’t look for the original part numbers of those capacitors, but I found a good Vintage Audio Repair (link obsolete 3/25) example that you can use as a reference to guide you through the products I listed, below. According to that article, the originals used wire-wrap termination, so be sure to look at the adaptation that was made with ring terminals. Note that the author used 22000uF replacements with good results, but you’ll have to decide if that will work for you as well. You will need to look at the overall fit of your replacements, though. The article photos shows how the author was able to use the terminals on the replacements vs. the cutouts on the board.
Here are some 15000uF Options with 100V to 200V ratings.

I noticed that the author used capacitors from the U36D series. Those appear to be obsolete, but we do have significant stock remaining for part number 565-4202-ND at the 22000uF level (they also made 15000uF). As mentioned before, be sure to look at the dimensions of these replacement capacitors. Everything is usually shown in a drawing or datasheet. Here is the document for the U36D Series, for example.
